Abstract
A generative process for the manufacture of three-dimensional mouldings is characterized by constructing the moulding stepwise by site-specific delivery of a structure-forming material in liquid form, where a second material is additionally delivered as a supportive material into regions which are intended to remain free from the structure-forming material, and is removed once the structure-forming material has been solidified. The supportive material exhibits low shrinkage upon cooling and is particularly stable in the cooled state and further exhibits low surface roughness.
